Dear Common,
Sorry I did not see you question. The first Vorka and the Berditchever. Not in a defied way – in a sainted way. This is not unique to chassidus. There were some by the Stolin split that chose to remain with the dead one until things sorted out. Old Lelov and early Chabad had such a side as well. Then there was the son who gave his dead father an aliya.
